vices for neutralizing shook, and has for its object to providemechanism in connection with motor vehicles of every type forneutralizing metallic vibration, wherein a nonmetall1c element 1slnterposed between the body of the vehicle and the frame forinterrupting and neutralizing the metallic vibrations.

In the drawings:

Figure 1 is a side view of a motor vehicle provided with the improveddevice;

Fig. 2 is an end view;

Fig. 3 is an enlarged detail of one of the non-metallic elements, withparts in section;

Fig. 4c is a front view of one of the hangers, with parts in section;

Fig. 5 is a vertical section through one of the elements and its hanger;and

Fig. 6 is a view similar to Fig 3 of a modified construction.

In the embodiment of the invention shown in Figs. 1 to 5, an inner frame1 and an outer frame 2 are provided, the frame 1 fitting within theframe 2, and the frame 2 is connected to the axles 3 and 4: by the usualsprings 5. A series of hangers is connected with the inner frame,eachhanger in the present instance being of turnbuckle construction,consisting of two alined rods 6 connected by a double sleeve nut 7, themeeting ends of the rods being threaded, as shown, to engage the nut.

The outer end of each rod 6 is engaged with a socket 8, and one of thesockets is on the under side of the inner frame and the other is on thehousing 9 to be presently described in detail. Set screws 10 arethreaded through the sockets into engagement with the rods for holdingthem in adjusted position, and it will be obvious that the length of thehangers may be adjusted by turning the double nut in the properdirection.

A second casing 11 is secured to the outer frame 2 directly above eachcasing 9, and it will be noticed, referring to Figs. 3 and 1,

. that the contour of these casings is approximately semi-circular, theflat side of the hanger 11 being secured to the frame 2, while the flatside of the hanger 9 is downward. Each casing has thus a rounded or areshaped surface, and these surfaces are adjacent.

A disk 12 of rubber or like flexible resilient material is arrangedwithin each casing, and these disks are connected by a belt 13 whichpasses over the disks in the same manner that a belt passes over a pairof pulleys. The disks are heldfrom rolling movement in the casings bymeans of screws 14 which are passed through the front of the casing andthrough the disks into engagement with the rear or inner wall of thecasing.

Referring to Figs. 3 and 5, it will be noticed that the front or outerwall of each casing 9 and 11 is slotted transversely, so that a portionof each disk and a portion of the belt at the disk is visible. The frontportions of the casing are detachable as shown, to permit removal of thedisk when desired. and the rounded surfaces of the casing are slotted topermit the passage of the belt.

In the embodiment of the invention shown in Fig. 6, the casings 15 and16, which correspond to the casings 9 and 11, are rectangular inoutline, and instead of disks 12 there are provided blocks 17 which havea flat or plane surface for engaging the end of the casing and a roundedsurface for engaging the end of the belt 18. The blocks are held frommovement in the casings by means of screws 19 which correspond to thescrews 14L of Fig. 5.

As many of the hangers may be provided as may be necessary, in thepresent instance six being provided, two at each side of the frame andone at each end. Thus the inner frame which carries the body of thevehicle is suspended from the outer frame, by the belts which are ofleather or like flexible non-metallic material, and the belts engage theresilient blocks or disks, which provides not only an interruption ofvibration, but provides resiliency as well.

- I claim:

1. In a motor vehicle, a device for neutralizing shock, comprising aframe adapted for connection with the body, a second frame connectedwith the running gear, a resilient non-metallic connection between theframes, said connection comprising hangers on one of the frames, eachhanger supporting a casing and the other frame having a casing ad jacentthereto, each casing carrying a disk of resilient material, and a beltof flexible material engaging each pair'of disks and connecting thesame, said hangers being adjustable in length, each consisting of asection detachably connected with the frame and another sectiondetachably connected with the casing, and a turnbuckle connecting theadjacent ends of the sections.

2. In a motor vehicle, a device for neutralizing shock, comprising aframe adapted for connection with the body, a second frame connectedwith the running gear, a resilient non-metallic connection between theframes, said connectioncomprising hangers on one of the frames, eachhanger supporting a casing and the other frame having a casing adjacentthereto,

copies of this patent may be obtained for five cents each, by addressingthe each casing carrying a disk of resilient material, and a belt offlexible material engaging each pair of disks and connecting the same,said hangers being adjustable in length.

3. In a motor vehicle, a device for neutralizing shock, comprising aframe adapted for connection with the body, a second frame connectedwith the running gear, a resilient non-metallic connection between theframes, said connection comprising hangers on one ofthe frames, eachhanger supporting a casing and the other frame having a casing adjacentthereto, each casing earryin a disk of resilient material, and a belt offlexible material engaging each pair of disks and connecting the same.
